BACKGROUND OF THE INVENTION This invention relates to a food-depositingapparatus and particularly to an automatic means, and apparatus forapplying or depositing ingredients upon a base member such as pizzamaterial upon a pizza crust or base. The manual processing of pizza,particularly for frozen pizza which is sold through grocery stores andthe like, is relatively time-consuming and expensive. Further, qualitycontrol is extremely difficult to obtain with the manual application andprocessing. A highly satisfactory, automatic pizza-forming apparatus isdisclosed in U.-S. Pat. No. 3,368,501 which was issued to Harvey G.Kuhlman on Feb. 13, 1968. As more fully disclosed in such patent, anautomatic apparatus is provided for sequentially applying the variousmaterials to a pizza base including automatic application of sauce,meat, shredded cheese and the like. The illustrated embodiment of thatpatent includes an open transfer apparatus in the form oflaterally-spaced belts for transfer of the material through the sauceapplicator and the shredded cheese applicator. The open structure isdesirable in allowing excess material to drop through the transferapparatus for recovery and the like.

SUMMARY OF PRESENT INVENTION The present invention is particularlydirected to an improvement in the food-distributing apparatus such asshown in U. S. Pat. No. 3,368,501 and, in particular, to an improvedtransfer means forming a part of the apparatus for supporting of thebases or the like while permitting excess material to drop through to asuitable recovery means. Generally, in accordance with the presentinvention, a plurality of spoked or tined supports define a transfermeans for transferring of the pizza bases or the like through the fooddepositing units.

In the preferred construction, the several tined parts are formed of asuitable stainless steel or the like to permit ready cleaning thereof. Aplurality of spaced shaft supports extend between a pair of longitudinalframe members. Each of the shafts is provided with a plurality oflaterally spaced tine groups with each group similarly circumferentiallydistributed about the shaft. The tined groups on the respective adjacentshafts are offset and overlapped to minimize the spacing between thetined groups and thereby provide a convenient support for pizza basesand the like. The shafts are coupled to a suitable drive such as acommon chain drive and continuously rotated in a corresponding directionto continuously move the transfer bases'through the appropriatefood-depositing units. In particular, the open structure defined by thetined supports is adapted to incorporation into the sauce applicatorand/or the cheese applicator to provide the open structure immediatelyin the applicating area to permit removal and/or recovery of the excessfood deposited upon the passing bases.

In a highly improved structure, the sauce applicator includes apressurized sauce spray head located within an open bottom enclosuremounted above the tined transfer means. A sauce recovery means isdisposed beneath the sauce applicating enclosure. The spray head ispreferably provided with a fluid cleaning means to prevent clogging ofthe nozzle, such as an air-operated piston cleaner. The spray headdeposits predetermined amounts of sauce across the transfer means forapplication in proper timed relation to the pizza bases. The ex cesssauce is recovered by the recovery means for recy cling andreapplication to subsequent pizza bases. The tined transfer meansextends from the sauce applicator to the infeed end of the shreddedcheese applicator and forms a part thereof which may otherwise generallycorrespond to that of the Kuhlman patent. The meat applicator ispreferably similar in structure to that disclosed of the cheeseapplicator construction shown in the Kuhlman U.S. Pat. No. 3,368,501 orthe like, where the bases are to receive a predetermined quantity ofdistributed grated meat. In the meat applicator, means are provided tocool the grated meat and improve the mtering thereof.

The present invention has been found to provide a highly reliable meansfor transferring of the bases and depositing of highly accuratelymetered amounts of sauce, cheese or the like, while permittingconvenient recovery of the excess material. The tined transferstructure, particularly when .made of stainless steel or other readilycleaned material, permits convenient cleaning of the apparatus with ahose or the like.

FIG. 9 is an enlarged fragmentary view of the meat applicator shown inFIG. 1.

Referring to the drawing and particularly to FIG. 1, the invention isillustrated in connection with a pizzaforming apparatus, including asauce applicator I mounted to the infeed end of a cheese applicator 2,which is essentially constructed in accordance with the teaching of theKuhlman U.S. Pat. No. 3,368,501, and a meat applicator 3 mounted to theoutfeed end of applicator 2. An infeed pizza base belt 3a is mounted tothe input side of the sauce applicator 1 and is adapted to transfer aplurality of pizza bases 4 as an aligned row into the sauce applicator.If desired, of course, single pizzas can be sequentially fed through thesauce applicator l and the cheese applicator 2. The advantage ofproviding the side-by-side construction, of course, is to substantiallyincrease the production rate. The pizza bases 4 are passed through theapplicators l, 2 and 3 to receive metered amounts of sauce, cheese andmeat, respectively, and removed through a suitable transfer belt fromthe discharge end of the meat applicator 3. The infeed'belt 3 and thedischarge belt 5 are thus disposed to the opposite ends of the foodapplicating means of the apparatus and may be formed as generally flat,continuous surfaced belts to transfer the pizza bases 4 to and from theapplicating units. The belts 3a and 5, as well as the other exposedelements of the apparatus, are preferably formed of a stainless steel orthe like to permit convenient and ready cleaning thereof. The pizzabases 4 are transferred through the food applicating portions of theapparatus 5 by similarly constructed special conveyor or transfe'rmeans6 and 6a aligned with the food depositing areas and particularly formsan important improvement in accordance with the present invention,

More particularly, the conveyor or transfer means 6 and 6a include aplurality of similar tined rotating supports 7 which are longitudinallyspaced to define an improved open conveyance structure for carrying ofthe pizza bases 4 through the sauce applicator I, the infeed end ofcheese applicator 2 and the meat applicator 3, in the illustratedembodiment, for receiving of the respective food materials. The transfermeans 6 extends through the sauce applicator 1 and the infeed end of thecheese applicator 2 while the similar transfer means 6a extends throughthe meat applicator 3.

Generally, in accordance with the illustrated embodiment of the presentinvention, the tined rotating supports 7 are journaled within spacedside frame members or units 8, suitably supported above ground level.

Each of the rotating supports 7 is similarly constructed and includes asupporting shaft 9 secured at the opposite ends in suitable, rotatingbearings. 10 mounted respectively in the side frame units 8. The one endof the shaft 9 extends through the frame unit 8 and into a generallyclosed drivehousing 11. A sprocket and chain drive unit 12- is coupledto each end of the shafts 9 within the housing 11 to provide forsimultaneous and corresponding rotation of the shafts 9. The chain driveunit 12 may be coupled to a suitable drive pulley or the like, notshown, which, in turn, is coupled to and driven in synchronism with themain drive system for the belts 3a and 5. If desired, of course, anyother suitable independent or separate drive can be provided for therota tion of the supports 7.

As most clearly shown in FIG. 4, each of the rotating supports 7includes groups of tines or prongs 14 secured to the shaft 9 with eachgroup including a plurality of individual tines or prongsequicircumferentially distributed about the shaft 9. Thus, in theillustrated embodiment of the invention, six equicircumferentiallyspaced tines 14 are secured to the shaft and define sequentiallypresented engaging ends to the pizza bases. The tine groups 14 inadjacent rotating support 7 are axially offset midway between adjacentgroups of the adjacent support, as shown in FIG. 2. Further, the shaftsare longitudinally spaced and the length of the tines 14 are such thatthe tines of adjacent supports 7 overlap, as shown in FIG. 3 at 15. Thismaintains an open structure while minimizing the space or openingsbetween adjacent supports and providing an improved continuous supportfor the pizza bases 4. Thus, there is not a continuous groove-likedepression formed in the supporting or transfer means 6 between thebelts 3a and 5.

As shown in FIGS. 1 and 2, the infeed belt 3a is mounted on a pulley 16adjacent the transfer means 6 and thus the supporting surface is spacedfrom the tine supports 7. The gap therebetween is shown closed by acoupling rollers 17 rotatably mounted within the side frames and coupledthrough to the chain drive unit B2 of the tine supports 7. A fixedpronged spacing unit 18 is secured between the frame members andincludes a plurality of supporting pins 19 extending toward the infeedbelt. Glass, plastic or similar smooth surface fingers 20 are secured tothe pins and project forwardly with the underside of the fingers 20tapered and extended into essentially sliding engagement with the belt3. This provides a continuous rod-like support from the belt 3 tothecoupling rollers 17 from 'which the pizza bases are transferred tothe rotating tined supports 7.

The opposite end of the transfer end may be similarly constructed totransfer the pizza bases from the transfer means 6 to an intermediatedischarge belt 21, forming a part of the cheese applicator 2 andcarrying of the pizza bases 4 therethrough and depositing them upon theinfeed end of the transfer means 6a for passage through the meatapplicator 3.

In the illustrated embodiment of the invention,-the sauce applicatorincludes an upper enclosure or hood 22 generally in the form of an opentop and bottom tubular housing or enclosure which extends completelyacross the leading end portion of transfer means 6. A two-pieceremovable top cover 23 is provided to enclose the discharge end of asauce applicating gun 24. The bottom of the hood 22 is completely openand allows transfer of sauce 25 from the nozzle 26 of gun 24 to thepizza bases as they move beneath the hood 22. In the illustratedembodiment of the invention, the gun 24 is secured by a suitable braceor support 27 to the front wall of the hood 22 to generally, centrallylocate the gun 24. The gun extends through the two-piece top cover 23with the lower end interconnected to a pressurized sauce source line 28.The gun 24 is mounted within the housing with the discharge nozzle 26directed toward the open-bottom. This directs the sauce downwardly ontothe pizza bases 4 to insure an even application of the sauce onto therespective bases 4 as they pass beneath the bottom opening of the saucehood or enclosure 22. A recovery unit shown as a pan 29 is mountedimmediately below the transfer means 6 in alignment with the bottomopening of the enclosure 22 to recover any of the sauce material whichfalls through the transfer means 6. The pan 29 may be part of anautomatic sauce recycling means, part of a wheel truck unit, or thelike, for removal and return to the source.

The gun 24 is a suitable pressure operated unit wherein the sauce 25 isforced through a main feed opening 27a in the nozzle 26 under a selectedpressure and is distributed downwardly and laterally across the transfersupport to properly deposit a uniform layer of a preselected amount ofsauce upon bases 4 as they move through the hood 22. In the illustratedembodiment of the invention, the gun 24 is generally an elongatedcylindrical unit having the nozzle 26 at the lower end and the saucehose 28 secured to the unit immedi ately adjacent the nozzle 26. As mostclearly shown in FIG. 5, the gun 24 includes an air cylinder piston 30secured to the outer end of sauce gun 24. The piston shaft extendsthrough gun 24 and terminates in a cleaning pin 31 aligned with thesauce opening 27a. A fluid pressure source line 32 isconnected to theunit 30. A control valve 33 selectively connects the line to a highpressure source, not shown, to force the piston assembly forwardly withpin 31 moving through opening 27a under a sufficient pressure todislodge any hardened sauce. If the nozzle 26 should therefore becomeclogged by dried sauce or the like, the operator can readily clean andopen the nozzle 26 by momentary application of pressure to line 32 tomove the pin 31 through the opening 27a and positively discharge anyclogging sauce.

Thus, as the pizza bases 4 move into the enclosure, the sauce 25 isapplied. The sauce covered pizza bases 4 are then moved by thecontinuous tined transfer means 6 into the cheese applicator 2, which isgenerally constructed as shown in the Kuhlman US. Pat. No. 3,368,501 andwhich is only briefly described herein. In the illustrated embodiment,an endless cheese metering belt 34 is mounted longitudinally of andimmediately above a transfer belt 35 extending between the trailing endof the transfer means 6 and the leading ends of transfer means 6a. Theshredded cheese 36 is deposited as spaced mounds on the upper surface ofthe cheese metering belt 34. Where the cheese is deposited in a mound,as shown, a single distributing tine 36a may be mounted to movelaterally across the belt and distribute the cheese. A pneumaticcylinder unit 36b is shown coupled to drive the tine 36a. A tinedmetering element or unit 37 is mounted immediately above the dischargeend of the cheese metering belt 34 and a rake or smoothing means 38 isprovided forwardly thereof to provide for continuous spreading andmetering of selected amounts of cheese from the cheese belt onto thepizza bases 4 in accordance with the rotation of the belt 34 and thetined metering means 37. Thus, as the pizza bases 4 pass beneath theinfeed end of the cheese belt 34, they are supported by the trailing endof the transfer means 6 which forms the input end of cheese applicator2. The shredded cheese 36 is deposited on the sauce-covered bases 4 asthey move beneath the input end of the belt 35 with any excess cheesefreely passing downwardly through the tined transfer means 6 and onto arecovery means such as an accumulator pan, a transferring conveyor orthe like.

In the illustrated embodiment of the invention, a vertical shield 39 issecured to the forward end of the cheese applicator 2. The shield 39 isa plate-like member which extends from immediately above the plane ofthe transfer means 6 and extends upwardly with the upper end suitablysupported to the cheese applicator framework. The shield 39 prevents theshredded cheese from being thrown into the sauce unit 1.

In the illustrated embodiment of the invention, an improved cheeserecovery and supply system is illustrated for use in connection'with agravity-depositing cheese applicator or the like. Generally, a stainlesssteel recovery belt 40 is mounted extending transversely of the cheeseapplicator and immediately beneath the cheesedepositing infeed endthereof in FIGS. 1 and 2. The recovery belt 40 is continuously revolvedin synchronism with the operation of the cheese applicator through aseparate or common drive system. The shredded cheese which fallsdownwardly between the tined supports 7 is carried by the recovery beltlaterally outwardly from the cheese applicator 2. The outer end of therecovery belt 40 overlies the lower end of a cheese supply conveyingbelt 41 which extends from beneath the recovery belt 40 upwardly andterminates in overlying relationship to the upper end of the main cheeseapplicator 2. This provides for automatic recovery and recycling of anyexcess cheese deposited and passed through the support. This same feedsystem is employed to supply shredded cheese from a special cheeseshredding apparatus which includes a cheese supply unit 43 and a cheesegrater 44 adapted to shred blocks of cheese and deposit them upom thetransfer and recovery belt 40.

As most clearly shown in FIGS. 6 and 7, the cheese supply unit isgenerally a rectangular, open-top slide member 45 which extendsdownwardly from above the upper end of the cheese grater 44 to the floorlevel. The upper end of the slide 45 is open to permit transfer ofcheese therefrom into the grater 44. An encircling sup port collar 46 isslidably mounted encircling the slide 45 as such. A plate 47 is hingedto the upper collar portion or bar 48 spanning the open top as by hinge49 and depends downwardly therefrom into the slide 45 and spans thedistance between the side walls. The hinge 49 is constructed for one-waymovement which permits the plate to pivot upwardly in a counterclockwisedirection from the normal depending position. A stop member 50 securedto the top bar is located behind the plate to prevent it from pivotingupwardly in a clockwise direction. Appropriate blocks of cheese 51 aredeposited within the slide 45 with the collar 46 retracted, and with theplate 47 depending downwardly into the slide. A hydraulic piston unit 52or the like is coupled to the bottom arm of the collar 46 and actuatedto move upwardly, thereby moving the plate 48 into engagement with andforcing the cheese blocks 51 upwardly and through the upper end of theslide 45.

The upper end of the slide 45 is provided with an automatic cheeseslicer shown including upper and lower support bars 53 and 54 secured tothe top and bottom of the slide. A cutting wire 55 is threaded throughthe bars to define a plurality of laterally spaced cutting elements.Thus, as the block of cheese 51 is forced upwardly through the upper endof the cheese slide 45, the wire 55 defines an automatic cutting meanswhich automatically cuts block 51 into a plurality of relatively smallstrips. The cut cheese is fed by gravity into the cheese grater 44 forreducing the cut cheese to the desired shredded cheese condition. Theshredded cheese is passed to the recovery belt 40 and fed therefrom tothe supply conveying belt 41 for transfer to the cheese applicator 2.

In the illustrated embodiment of the invention, the hinged plate 47allows the loading of the slide 45 during the terminal portion of thefeeding of the block 51 into the grater 44. Thus, with the collar andplate 47 moved upwardly toward the upper end of the slide 45, new blocksof cheese may be deposited in the lower end of the slide 45. As mostclearly shown in FIG. 8, a stop wall or member 56 protrudes from theside walls of slide 45 to support the cheese blocks 51. The width ofplate 47 is less than the width of the slide 45 to move freely past themembers 56. When the collar 46 is retracted, the hinged plate 47 willpivot upwardly and pass over and past the cheese blocks, then pivotsdownwardly to pick up the next group of blocks 51. The

stroke or movement of the plate 47 is approximately one half of thelength of the slide 45. Spring loaded and pivotally mounted stop walls57 are secured within openings 58 in the sidewalls of the slide 45 atthe midpoint. The walls 57 have cammed or angled surfaces 59 projectinginto the path of the upwardly moving blocks. The leading cheese block51, therefore, pivots the stop wall 57 outwardly to allow free passageof the cheese blocks 51. The hinged plate 47 is slightly spaced from thesidewall and allows the stop wall 57 to pivot outwardly behind thecheese block 51 immediately adjacent the plate 47. In operation, theplate 47 is moved upwardly to locate the last cheese block 51 in frontof the stop wall, retracted to pick up the next group of cheese blocks,and then moved upwardly to again force the previously located blocks 51outwardly through the cutting wires 55. This has been found to provide avery simple, reliable and economical means for continuous feeding of thecheese into the applicator as'required.

The shredded cheese is continuously applied to the pizza bases 4 in veryaccurately metered amounts and thecovered bases are carried therefrom bythe transfer means through the cheese applicator 2 and into the meatapplicator 3. The meat applicator 3 may be constructed in any desiredmanner, such as shown in applicants issued US Pat. No. 3,368,501. In theillustrated embodiment of the invention, an alternative and novel meatapplicator is shown for applying shredded or granulated meat which hasbeen partially or wholly cooked. The meat applicator 3 includes an upperendless conveyor belt 60 overlying pizza base transfer conveyance 6a.The belt 60 is preferably a continuous stainless steel belt mounted on apair of axially spaced pulleys 61. The meat is deposited thereon asawholly or partially cooked ground or granulated meat 62 from a suitablepressurized meat source 63, such as a positive displacement pump feedinga hopper. The granulated meat extends laterally across the stainlesssteel belt 60 and is carried therefrom toward the infeed end of the meatapplicator 3. The meat 62 is applied by gravity and a special meteringunit from the forward end of the belt 60 onto the pizza bases 4 as theypass therebeneath.

In accordance with the illustrated construction, the meat 63 is providedat a relatively elevated temperature to permit convenient pumping ortransfer of the meat 63 onto the conveyor belt 60. Suitable coolingmeans are provided to cool the meat 63 as it is transferred forwardly tothe discharge end of the conveyor. Cooling plates 64 and 65 are shownabove and below the belt to provide for cooling of the meat 63 as itpasses therebetween. For example, the cooling plates 64 and 65 may besuitable sealed brine plates or apertured plates interconnected to asuitable source of cold air or other fluid with nozzles for directingthe cold air to the opposite sides of the belt. In the latter, thebottom plate 65 would provide a continuous stream of cooling air to theunderside of the belt 60, while the upper plate 64 would provide acontinuous blanket of cooling air directed downwardly over the meat 63carried thereby.

At the forward end of the meat applicator 3, a special feeding andmetering unit 66 is mounted and includes a smooth surfaced roller ordrum 67 which is rotatably mounted. Drum 67 rotates with the portionadjacent belt 60, moving in the same direction as belt 60 andestablishes a selected leveling of the meat on the belt 60.

As most clearly shown in FIG. 9, the feeding and metering unit 66further includes a pair of oppositely rotating and overlapping bladed ortined metering members or beaters 68 and 69. The metering beaters 68 and69 are located immediately forwardly of the leveling drum 67 and withthe overlapping portion slightly forwardly of the forwardmost end of theendless belt 60. The beater 68 adjacent the drum 67 is only slightlyspaced from the belt 60 and rotates in the opposite direction. Thebeater 68 includes a plurality of closelyspaced blades or tines, similarto the cheese applicator or conveyor 6 and picks up the granulated meat62 and carries it around into the other beater 69. The second beater 69is located slightly lower than the first beater, and meshes with it. Thetines of the beaters 68 and 69 are offset axially of each other, similarto the tined supports 7 and the second beater 69 rotates at a higherspeed. In an actual unit, the second beater 69 rotated at twice thespeed of the first. The granulated meat 62 is thus leveled by the drum67 and removed by the first beater 68 and carried around and at leastpartially transferred to the second beater 69 to be deposited as afree-falling column 70 of granulated meat spaced slightly from theforward end of belt 60, as most clearly shown in FIG. 9. Applicant hasfound that this permits accurate metering of the granulated or groundmeat.

The structure further is improved by heating of the leveling drum 67 tominimize the adhesion of the meat. In the drawing, a core electricalheater 71 is shown within drum 67. Further, a cleaning blade 72 issecured in sliding engagement with the surface of the drum 67immediately above the first beater 68 to remove any meat adhering to thedrum. Similarly, a cleaning blade 73 is shown secured in slidingengagement with the forward end portion of belt 60 to remove any meatadhering thereto.

The shredded meat thus falls on the bases 4 as they pass beneath thefalling meat column. The meat that passes between the bases may berecovered in any suitable or desired manner. For example, an augerconveyor 74 may be mounted beneath the bed 6a to collect and convey therecovered meat from beneath the tined bed 6a for subsequent application.The auger-type c0nveyor may be employed for meat and, if desired,directly return the material to the meat supply 63 or belt 60.

In this manner, the pizza bases, after receiving the sauce and thecheese, are provided with an accurately controlled and predeterminedamount of grated meat with the completed pizzas passing from the meatapplicator and onto the discharge belt from which they may be passeddirectly to a suitable final processing and packaging unit, such as awater-film applicator, a blast freezer and the like.

The present invention thus provides a highly improved food-depositingapparatus particularly adapted for the formation of frozen pizzas andthe like. The apparatus essentially eliminates the manual laborassociated with the formation of pizzas and permits rela tively highquantity production.

The present invention has particularly been found to provide a highlyimproved and reliable system for supporting and transferring of thepizza bases or the like through food depositing units 1 and 2 at acontrolled, uniform speed while permitting convenient and economicalcleaning of the apparatus.
